# Tripo AI 3D Generator

> Tripo is an AI 3D generator from the company Tripo AI (founded by VAST). Kenerate AI's 3D Studio runs two of its engines: Tripo P2, released 21 September 2026 for native quad meshes in production pipelines, and Tripo H3.1, a high-detail engine from early 2026 that takes text, one photo or multiple views. Both produce PBR-textured models.

## Key facts
- Engines here: Tripo P2 · Tripo H3.1 (studio default)
- Released: P2: 21 Sep 2026 · H3.1: early 2026 (API snapshot 11 Feb 2026)
- Inputs: Text · 1 photo · H3.1 multi-view: front, left (+ back, right)
- Mesh: P2: native quads ≤25k or triangles ≤50k · H3.1: high detail, optional quad
- Textures: PBR; P2 tiers fast → extreme; H3.1 standard / detailed
- Files: GLB (both) · FBX (P2)
- Engine Meshy 7.1 (Meshy): inputs Text/Photo/Multi-view; files GLB, FBX, OBJ, USDZ; typical about 3–4 min; Production assets with the finest Meshy geometry (2K / 4K), smart topology, rigging and animation.
- Engine Meshy 7 (Meshy): inputs Text/Photo/Multi-view; files GLB, FBX, OBJ, USDZ; typical about 3–4 min; Detailed game and product assets, with an Ultra detail switch, low-poly mode and auto-rigging.
- Engine Meshy 6 (Meshy): inputs Text/Photo; files GLB, FBX, OBJ, USDZ; typical about 3–4 min; Reliable textured meshes with a polygon budget you control — the engine 3D Studio started on.
- Engine Tripo P2 (Tripo): inputs Text/Photo; files GLB, FBX; typical about 3–4 min; Crisp, game-ready meshes with pro texture tiers up to Extreme and clean quad remeshing.
- Engine Tripo H3.1 (Tripo): inputs Text/Photo/Multi-view; files GLB; typical about 4–5 min; High-quality meshes, with detailed geometry and a four-view mode for exact shapes.
- Engine GPT-6 Astra (OpenAI): inputs Text/Photo/Multi-view; files GLB; typical about 5–6 min; OpenAI's general GPT-6 Astra model run as a 3D job — follows long, detailed briefs and up to 10 reference photos, returns a GLB with PBR textures at real-world size. The slowest engine.
- Engine Rodin 2.5 (Hyper3D): inputs Text/Photo/Multi-view; files GLB, FBX, OBJ, USDZ, STL; typical about 2–3 min; Studio-grade meshes from 2K to 500K faces, quad or triangle, with a HighPack for 4K textures.
- Engine Rodin 2 (Hyper3D): inputs Text/Photo/Multi-view; files GLB, FBX, OBJ, USDZ, STL; typical about 2–3 min; Clean, detailed meshes — the first photo drives the materials.
- Engine Hunyuan 3D 3.1 Rapid (Tencent): inputs Text/Photo; files GLB; typical about 1 min; The fastest geometry — an untextured (clay) GLB for quick blockouts, drafts and ideas.

## Steps
1. Open 3D Studio — Pick Text to 3D, Image to 3D or Multi-view.
2. Pick Tripo — Choose Tripo H3.1 for detail or Tripo P2 for clean quads.
3. Set options — Texture quality, PBR, quad, face limit, real-world scale.
4. Generate and download — Inspect and download GLB or FBX.

## In depth

### Timeline
Tripo H3.1's stable API snapshot is dated 11 February 2026 [23]. Tripo P2.0 was released on 21 September 2026 with native quad generation, face budgets, mesh editing and smart UVs on Tripo's own platform [24].

### Native quads vs quad remesh
Most engines generate triangles; a quad option then retopologises the result. P2 is described as producing quads directly, aiming for edge flow that follows the form [24]. In our tests P2 meshes were a few thousand faces while H3.1 passed a million — two ends of the same trade-off.

### Open source history
Tripo's maker released earlier research models such as TripoSR (with Stability AI) under the MIT licence; the production P2 and H3.1 models are not open source.

## FAQ
Q: What is Tripo AI?
A: Tripo is an AI 3D model generator from Tripo AI, founded by VAST. It turns text and images into textured 3D models.

Q: Is Tripo 3.1 the same as Tripo H3.1?
A: Yes — “Tripo 3.1” is the common name for Tripo H3.1, the high-detail model from early 2026.

Q: What's new in Tripo P2?
A: P2 (21 Sep 2026) generates native quad meshes for production, with face budgets up to 25k quads or 50k triangles.

Q: Is Tripo open source?
A: Tripo P2 and H3.1 are closed models. VAST has open-sourced earlier research models such as TripoSR and TripoSG under the MIT licence.

Q: Do I need a Tripo account?
A: No — Tripo runs inside Kenerate's 3D Studio on any paid plan or credit pack.

Q: Is Tripo AI safe to use?
A: Yes, as it runs here. You sign in to Kenerate only — no separate Tripo account — and each model is saved to your gallery as a standard GLB (plus FBX on P2) that opens in Blender, Unity or Unreal. Prompts are checked before a job runs, and adult 3D content is blocked.

Q: Which Tripo should I use?
A: H3.1 for detail and multi-view accuracy; P2 for light, clean meshes for games and real-time apps.

Q: Can I use Tripo models commercially?
A: Use generated models in your projects; check Tripo's terms for any limits on its engines' output.
